Colon Function

Includes: large intestine, rectum, and anus. Absorbs water and minerals. Formation and elimination of waste. Houses over 700 species of bacteria, some of which are considered friendly bacteria, that produce vitamin B12, Biotin, and K and protect us against harmful bacteria, virus, and fungus
